ISO 9073-6:2000 テキスタイル—不織布の試験方法—パート6：吸収 | ページ 2

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this part of ISO 9073 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

International Standard ISO 9073-6 was prepared by Technical Committee ISO/TC 38, Textiles.

ISO 9073 consists of the following parts, under the general title Textiles — Test methods for nonwovens:

• Part 1: Determination of mass per unit area
• Part 2: Determination of thickness
• Part 3: Determination of tensile strength and elongation
• Part 4: Determination of tear resistance
• Part 6: Absorption
• Part 7: Determination of bending length
• Part 8: Determination of liquid strike-through time (simulated urine)
• Part 9: Determination of drape coefficient
• Part 10: Linting (dry state)
• Part 11: Run-off tests
• Part 12: Demand absorbency

1 Scope

This part of ISO 9073 describes methods for the evaluation of some aspects of the behaviour of nonwoven fabrics in the presence of liquids. In particular:

• the liquid absorbency time;
• the liquid absorptive capacity;
• the liquid wicking rate (capillarity).

It should be noted that these different aspects of absorbency may relate to various end uses of the tested products.

The tests are not applicable to any fabric containing super absorbent materials.
